| 摘 要： | 舰船直流电力系统的短路电流在几ms内就可达到峰值,限流器必须快速检测并限制故障电流,从而有效抑制短路电流对系统的冲击。提出了基于电流变化率di/dt与电流幅值I双重判据的快速检测短路故障原理,以CPLD器件核心开发了保护装置,并对该装置进行了试验验证,试验结果表明,故障快速保护装置可以满足舰船直流电力系统的短路保护要求。

| Abstract: | Short circuit current of ship DC distribution system could rise to peak value in a few milliseconds.In order to restrict the impact of short circuit,current limiter must detect this fault quickly and limit the amplitude of short circuit current.The principles based on dual judgments including current changing rate and current value were put forward to implement the fast fault detection.The protection device was designed by CPLD(complex pro-grammable logic device) and test was made to testify this device.Tes... |
